:>Ideally, I would like to create all future data spaces with a size of 2GB, rather than 2GB OR 2GB-4K (when the returned ORIGIN value is NZ). I looked at assembler service reference manuals as far back as 1999, and they all state that a non-zero origin value (4K) is based on a processor dependency. I eventually found a vintage IBM-Amdahl presentation (1989) indicating the dependency is due to low-address protection being in effect when the PSF (Private-Space Facility) is not active. :>My question is... Is this still relevant 30 years later? Do any G10 or above customers run configurations where PSF is inactive? If you are already changing the code, why not change it to use 64 bit memory objects. That way you can get the exact size. -- Binyamin Dissen <bdis...@dissensoftware.com> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
